Access Alloy 400 Rod Stockist in India With Same-Day Enquiry Response

Every Monel 400 Round Bar leaving our Mumbai stockyard is PMI-checked before loading, so the chemistry on your packing list matches what's inside the bundle. Kanakratna Steelage forges, rolls and cold-draws this nickel-copper grade for marine, HF-acid and sour-service duty across chemical and offshore projects. An EN 10204 3.1 mill certificate travels with every consignment as standard, and that consistency is exactly why buyers keep returning to us as their trusted Monel 400 Round Bar Stockist in Mumbai.

Both our Mumbai units run press, GFM and closed-die forging alongside bar rolling and centreless grinding, so round, hex, square and flat forms all leave the same floor. We hold ISO 9001:2015 and AQSR-PED 2014/68/EU registrations, with an active IEC for cross-border shipment. Ahmedabad, Bengaluru, Chennai, Pune, Rajkot and Kolkata fabricators reorder from us for that same batch-to-batch consistency. Overseas, our export desk moves Alloy 400 Rod to 20+ countries spanning the Gulf, Asia, Europe and Africa on a standing sailing schedule.

Performance Data

Monel 400 Hex Bar Heat Treatment

Process Anneal
870–980°C (1600–1800°F), air or water cool
Stress Relief
540–565°C (1000–1050°F), 1–2 hours
Monel 400 is a solid-solution alloy, not precipitation-hardenable - annealing restores ductility after cold work, it doesn't build strength the way ageing does on Monel K-500.

Frequently Asked

Is Monel 400 Magnetic?

Curie Point: 21–49°CSlightly magnetic near/below room temperature, non-magnetic above it

Its Curie point sits at 21–49°C, so Monel 400 can read weakly magnetic below room temperature.

Buyer Questions

Monel 400 Round Bar FAQs

What is Monel 400 Round Bar made of?

63% minimum nickel with 28-34% copper per ASTM B164, plus controlled iron, manganese and carbon additions.

Is Monel 400 the same as Monel K-500?

No - K-500 adds aluminium and titanium for age-hardening, nearly doubling standard Monel 400's strength.

Is Monel 400 resistant to hydrofluoric acid?

Yes - Monel 400 resists both wet and dry hydrofluoric acid across nearly every concentration and temperature.

What determines the Monel 400 round bar price?

Order quantity, diameter, finish, testing level and current LME nickel-copper market rates set the price.

What is the Monel 400 round bar price in India right now?

It moves daily with nickel and copper rates - share your size and quantity for an ex-Mumbai quote.

Does Monel 400 require post-weld heat treatment?

No; as a single-phase solid-solution alloy, its strength and corrosion resistance don't depend on post-weld heat treatment.

Which industries buy Monel 400 Round Bar most often?

Marine engineering, oil and gas, HF-acid refining, chemical processing and valve and pump manufacturing worldwide.

What is the HS code for Monel 400 Round Bar, and do you supply mill certificates?

HS code 7505 12 20; every order ships with an EN 10204 3.1 mill test certificate.
